This locic, oper- Fig. 19 is a projectiveelevation of driving ated by foot, requires no special description. too

There is also a semicircular stand, B which serves to hold the foot ofthe trees in correct position for the action of the rubbing-tools. Fixedto the trees next to the turret are the plates A", with elongated faces.The stand B is so placed that the trees are free to be turned by handwhere the operators stand, and its ends are so rounded that if the treesare not correctly positioned by the operator within certain limits therevolution of the turret A causes the elongated face of the plates A" tostrike one of the rounded ends of the stand B and roll the tree intocorrect position, and remain there until removed from over 13 The post13 is mounted upon legs 0 O D D, as shown in Figs. 1 and 2, the legs 0 Ocarrying the rubbing and the legs D D carrying the jacking or spreadingmechanism. Through the lower part of the legs D D are the fulcra D D ofthe counterbalanced treadles D D which are connected by the rods D D tothe bell-crank levers D" D. These levers are pivoted at D D Theconnter-balances keep these parts when free in their extreme backwardposition, so thatwhen the turretAis revolved the lower ends of bars A Awherever their position, will pass clear of the upper end of thebell-cranks D D, and, deposing the treadle D will cause the upper end ofthe bell-cranks D D at some part of their forward motion to exertpressure upon bars A and jack or unjaek a shoe as required.

Adjustable on one of the legs 0 is the stand 0, Figs. 3, 4, 5, 6, 7, 8,9,which stand supports the operating mechanism for rubbing the sides,front, and foot of a shoe by vertically-reciprocating motion. Atool-face, d, is shaped so as to be adapted to the section upon which itis intended to work. It is secured to a rod, 01, which rod can beadjusted at will for length in the socket or sleeve (1 the socket dbeing itself pivoted at d to the reciprocating head E. On this socketabove the pivot d is extended the bar dflwhich, about midway of itslength, engages with the spring (i This spring d holds the tool-face dup to its work on the shoe. The part of the socket pivoted to head Eforms a stop, (see Fig. 9,) which prevents the spring d from throwingthe toolfaee d beyond the point at which it rests when it is in positionto begin its rubbing upon the shoe. (See Fig. 4.)

The heads E E are guided by the grooves E in the stand 0. They arereciprocated by the connecting-rods E and the cranks E. The tool-faces dare ad j ustable for the kind of work they are to perform. Sometimesthey move to a fixed line on the shoe and return, and sometimes theymove beyond the part of the shoe they are desired to rub and then return. In the latter case the tool-face cl must be raised above and awayfrom the edge of the leather until it has returned far enough to preventcontact with the edge of the leather and doing injury to the shoe. Toaccomplish this we use the heads E, driven by the cranks E and theconnecting rods E. These cranks E are fixed outside of cranks E and areset back in time five or ten degrees behind the cranks E". These cranksE cause the heads E E to travel about one-third farther than the heads EE, resulting in this: that when the heads E E have reached the extremelimit of forward motion, the heads E E are moving slowly toward them.

The curved pieces or cams e and c are at tached to E. These piecesengage with the extensions d" of sockets (Z and they are shaped to acton the extensions (2 by the different motions of the heads E", and thusto raise and hold the tool-faces governed by the extensions (1* awayfrom the tree and leather the desired distance and time. These curvedpieces could be so shaped that the tool-faces could be made to followthe contour of the tree during the whole of their motions. 4, work nextto the randline. They are pivoted in sockets like (Z without itsextension, and these sockets are so pivoted to the heads E E that theyhave a motion at right angles to that given by the pivots (i These toolsare so arranged that they can follow the curve of the rand or the curveof the tree. The motions of the joints of these tools arelimited bystops d the springs d acting against thestops at about an angle offorty-five degrees. The tool-faces d are prolonged so as to permitthemto ride on the plate F, when the action of the feed moves them towardit. This plate F is a thin plate of metal having an opening large enoughto admit the sole of the largest shoe of the series for which it isdesigned. It is curved to the average rand-line of that series andattached to the swinging frame F, hung at F on the stand 0. Thisswinging frame F carries the plate over the sole the proper distance, asshown by the dotted lines, Fig. 8, so as to allow the tools d to actnearly down to the rand-line of the shoe.

When the machine is in operation, the partial disks E, connected tocranks E,aet against the back edges of the swinging frame F, as will beunderstood by reference to Fig. 3, andkeep the plate F in correctposition.

Figs. 3 and 4 show the cams 0 made in one piece and shaped to the partof the tree they work under. They are fixed to the differential head Eto operate when desired the toolfaces carried by the head E. The feedingde vice of the tools carried by head E is the slotted piecef, attachedto the sliding part of the head E, and the crank f, fixed on the ratchetf, having its bearing on the fixed part of the head E. This ratchet ismoved one tooth each time the head E is nearest head E by the pawl f,fixed on head E".

Figs. 3, 8, and 9 show the feeding device of the tools carried by thehead E. These tools are swung around the bolt 9 as a center by the crankg, driven by the ratchet 9, having its bearing in the fixed part of headE, the pawl g, fixed at head E operating the ratchet The crank goperates in the slot The tool-faces d, Fig.

, proper times with their counterparts formed the cranks E in thedesired position and the limit, the ratchet It moves one tooth and theThe cranks E E, Figs. 3, 5, 6, and 7, are fixed to the shafts G, whichhave their bearings at G on the stand 0. These shafts are driven by theclutches G which slide on feathers set in them. The clutches engage atthe in the clutch-gears G, these gears having constant motion from thegear G and pulley G, carried on the main shaft G XVhen the gears G" arein motion and the clutches G in gear, the operation of stopping andstarting is as follows: Fixed to one of the clutches G is the revolvingspringpawl h, which at each revolution of clutchG" moves theratchet-wheel it, carried on the stand G, one tooth forward. Whenever Ithas moved the proper number of teeth the incline hflwhich is fixed uponit, e11- gages with inclineh, an incline fixed upon the double-eurvedwedge h", and moves and holds the curved wedges It close to the clutchesG In the correct position on the circumference of the clutches G to drawthem out of gear from G are fixed the inclines G As these inclinesrevolve over the curved wedges h the clutches are forced back againstthe spring G and withdrawn from contact with G, leaving wedges it lockedin position. To start the mechanism, there is provided the levercarrying a spring-pawl, h, which pawl engages with the ratchetteeth ofratchet-wheel h at all times, acting as a retainer to prevent incline Iffrom moving back. This lever 7&5 moves around the same pin h aroundwhich the ratchet 7i revolves. Itis held back hy'the spring 7r. Themotion of this lever if is so limited that it can only be swung a littlemore than the angle of one ratchet-tooth (See dotted line, Fig. 5.)\Vhen we swing lever If its inclines If it pass by each other, leavingthe springs it", behind the curved wedges h free to move those wedgesfrom under the incline G, thus allowing the spring G to move one of theclutches G into its counterpart in one of the clutch-gears G, resultingin one of the toolcarryingheadsmoving toward theshoe. WVhen this headhas reached its full inward movement, the other clutch drops in and theheads move in unison until they have performed the set number ofstrokes, when they stop, as before.

To insure the feeding devices stopping at the same position each time,the ratchet It is made with one more tooth than the feedingratehetsf 9for there is one tooth of ratchet it not moved by pawl h.

The stand 0 Figs. 10 to 20, carries the toe and back rubbing tools.These tools move apart to allow the trees to be moved, as do those forthe sides and front, and oscillate about sixty degrees, their center ofoscillation being adjusted to the length of the shoe by the rests H Hcontacting wit-h the toe and heel. The tool-facest' are pivoted at t" tothe spindles These spindles slide in the bearings i and the tool-faces iare pressed against the shoe by the springs i", around the spindlesbetween the tool-faces and the ends of the bearings. Stops i regulatethe forward motions of the spindles The tools for the toe have theirbearings pivoted at i", and the springs i give angular elasticity tothese tools when working down on the toe, stops limiting the motionaround the pivots t. The tools are mounted on carriers H Figs. 17 and18, and H Figs. 14 and 15, arranged as shown. It the shape and length ofthe leg part of the shoe require it, any number of tools can be removedfrom carrier H. The carriers H II are provided with pivots or shafts. HH These pivots move in bearings 11 H and the bearings have verticalmotions in the slides H, which are fixed to the plate Hof the stand 0Figs. 10, 12, 13, 16, and 19 show the means for oscillating thetootcarriers H H. Fixed in the bearings H H by the keepers i so thatthey can oscillate, are the levers or clamps I. Fitted to the levers Iat I are the small parts of the pivots H H which are free to slideforward and backward on feathers I fitted to the keyways I. To the outerend of the levers I are jointed the connecting-rods I, the opposite endsof these rods being jointed to the common crank 1 fixed on the mainshaft 1". Fig. 16 shows how the revolution of crank I oscillates thelevers I and the parts fixed to them. The feeding of these tools isaccomplished by the pivots H" H sliding in and out through the bearingsH H and levers I, when the levers are moving, by the following meclvanism, as shown in Figs. 10, 12, 13, 16., and 17: Fixed on the smallpart of pivots H H between the collars J, so that they are free torevolve, are the cams J J, whose paths are shaped to give the desiredforward and backward movements to the pivots. One side of the canrpathsis provided with the desired number of ratchet-teeth. Fixed to thebearings H H are the barsjj, with the cam rolls jj at their outer endsand the retainer'pawls j passing through them over the ratchetteeth.livoted to the lever l. at I is the feedpawl 1 held down in theratchet-teeth of cams J J by a spring. (Not shown.) These feedpawls I ateach full oscillation of the lever I move the ratchets one tooth. Theratchets following the curve of the cams and the rolls being fixed, therelations of the feed andretainer pawls with the ratchet-teeth remainunchanged as the cams move the pivots H H in and out the desireddistance.

Figs. l0, 11, 12, 13 show the devices used to move the tools to and fromtheir operative positions. Bearings H H and their respective mechanisms,with a common source of motion, the crank 1 are moved to and from eachother in the slide H by the links 7t is, Fig. 11.. These links areconnected to the levers it It, which levers are pivoted to the plate Hat it" If, lever it being connected to lever It by the red It, as shown.The lever 70' has the counterbalancespring k" of the desired tension todepress the tools carried by carrier IF to their work, a

spring, it acting directly for carrier H The slot in the link 75provides for the varying length of shoes. The crank K, revolved underthe lever by the ratchet it at the proper time, brings its roll K incontact with the lever It, and by successive steps raises lever 76 toits highest position, and drawing bearings H H? apart, as will beclearly understood from Fig. 11, crank K then stopping its motion.

' 1n the stand L the main shaft 1 has its bearing, with the crank Ifixed to its inner end. (See Figs. 10, I3, 16.) Outside of this bearingthe driving-pulley L runs. A clutch, L, fixes pulley L to the shaft atthe proper times. On the inside of this pulley L, which is always movingwhen the machine is in operation, is formed the eccentric L. Thiseccentric causes the long pawl, L, to move the space of one tooth of theratchet K at each revolution of the pulley L, pawl L being held to theratchet by the spring Z.

If it is desired that the tools operate ten full strokes on the shoe,the ratchets on the cams J must have ten teeth. Then to use the timerepresented by three revolutions of pulley L for the tools to move downand start and two revolutions of pulley L for the tools to stop and moveaway, the ratchet K should be spaced for fifteen teeth, with one leftblank, as shown in Fig. 12. Ratchet K and crank K are fixed on the shaftK, which revolves in the stand K", which is fixed 011 plate I1. Betweenthe stand and the ratchet K is mounted on the shaft K the lever K,carrying the retainer-pawl K the lover I being held back against a stop(not shown) by the spring Z The clutch-lever is pivoted to the stand Land drawn in by the spring Z. On the side of the ratchet K is formedtheelevated semicircle K whose ends terminate with inclines, Figs. 10,12, 20. This semi-circle K, by contact with the incline L of theclutch-lever, forces the clutch away from the pulley L, as willbeclearly seen, Fig. 20.

hen the crank K is holding the tools farthest apart, the long pawl L ismoving backward and forward over the blank space of ratchet IQ. Raisingthe lever K causes the ratchet K'- to revolve one tooth,-the long pawl'L coming into action. At the end of two revolutions of thedriving-pulley L the heel and toe rests H H are resting on the shoe, andthe inclined end of the semi-circle K has passed clear of the incline Lon the clutchlever L \Vhen the spring Z has drawn the clutch L into Land the crank I has made ten revolutions, the inclined semi-circle,which is moved by the ratchet K", forces the clutch out of gear just asthe roll K on the crank K is brought in contact with the lever W. Theremaining teeth of the ratchet move the tools apart and the pawl L movesagain over the blank space of the ratchet.

The shoe trees N are provided with springs N Fig. 21. These springs whenat rest hold the side of the shoe. The object of these springs is topermit the tools which are carried by the head E, and which work fromthe end of the toe toward the end of the tongues, to work to the endsand sides of the tongue without coming in contact with the flap sides ofthe shoe. These springs have their tension so regulated that they yieldto the pressure of the tools carried by the head E, so that these toolscan finish the side or flap part of the shoe by their motion from theheel part of the shoe toward the toe.
